inside-ofthefbumper guard il..` Although this, internally threadedmember 25 may be fastened atany position in the: bumper. guard Il', itYis. ad- Visablefto fastenfit to one of the` ends or one of therspaced`rod guide'portions 2I and-2.2. InFig.-

ures 2 and 3- IA have illustrated the internally threadedmember 25asbeing fastened in the bumper; guard. member at the top end 2l there` loforinthe-spaced rod:y guide portion 2l, thus Figurisaeross-sectionalyiew-'of'amodificae .7; .-f integrally making themember 25 a part of the rod guide portion.

weer The internally threaded member 25 is illustrated in Figures 2 and 3as` being a cylindrical body having a threaded opening 26 therein. A1-though any suitable design or shape of internally threaded member may beused, the cylindrical member has been found to be the most economical tomanufacture and fasten into the guard member. As with most bumper guardmembers, the front of my guard member is curved and has side walls 21and 28 extending in planes substantially vperpendicular to the bumperand over the bumper I6. By designing the front of the bumper guardmember I1 circular to match the outside surface of theinternallythreaded member 25, I have provided a plurality of points ofContact between the bumper guard I'I and the internally threaded member25. The internally threaded member 25 may be spot welded to the sidewalls 2l and 28 on opposite sides thereof and also on the front of thebumper guard member to securely fasten it thereto.

The elongated threaded jack rod I9 which extends through the opening 23and 24 inV the bumper guard-member I7 is removably threadable throughthis internally threaded member 25. The openings in the spaced rod guideportions (generally the top and bottom ends of the bumper guard) and thethreaded opening 2B must be coaxialiy aligned to permit the jack rod I9to be extended therethrough. A bushing 2D may be fastened to the guardmember at the openings in the rod guide portions to provide an axiallylonger bearing surface for the threads on the jack rod i9. With thisbushing 2B the threads Will not bind in the rod guide portion.

When the jack rod is extended th-rough'the bumper guard, as isillustrated in Figure 2, there is no Way in which the jack rod I9 andthe bumper IS of the automobile body IIlcan become disengaged. The jackrod I9, in extending through the openings in the space rod guideportions of the bumper guard I'I, is always fastened to and disposed atan angle to the bumper I6. I have found it advisable to provide a Wrenchengageable portion 29 on the top end of this threaded jack rod I9 and anextended non-threaded portion 3o on the bottom end of the jack rod I9.This wrench'engageable portion 29 is preferably constructed to receivethe same Wrench as is used to remove thenuts on the wheel I2.V AlthoughI provide the jack rod IQ'With the Wrench engageable portion 29 it isunderstood that a hole through the'jack rod I9 for receiving a bar or ajackv rod I9 in substantiallyV avertical position handle or any othersuitable means Well known f in ther art may be substituted to providemeans for threading the jack rod I9 through the internally threadedmember 25 and thereby raise the automobile body Il] off the ground.

The non-threaded'portion 30 on the other end of the jack rod I9 is of alength slightly less than the distance between the Ainternally threadedmember 25 and the ground when the car has a fiat tire. In omitting thethreads from this end 3B the operator of the jack does not have to turnthe jack rod I9 as many times before the mem'- ber 3G engages theground. In VFigure 2, I have illustrated in cross section a smallplate3l which may be rested on the ground to provide abetter support forthe end 30 of the jack rod i5.

In Figures Lland 5 of my drawings, I have illustrated'a modification ofmy invention in which the bolt used for fastening the bumper guardmember Il' on tothe bumper I6 is internally threaded. This bolt isdesignated by the ref-V while it is supporting the automobile body I0.This bolt 40 illustrated in Figures 4 and 5 is preferably welded to theWalls 21 and 28 of the bumper guard I1 in the same manner as theinternally threaded member 25 of Figures 2 and 3.

The elongated threaded jack rod I9 and the ground plate 3l are usuallycarried in the tool kit or trunk of the automobile. When the driverfinds it necessary to jack one of the Wheels olf of the ground, heremoves the threaded jackrod IS and drops it into Vthe bumper guardclosest to.

suspend the Wheel I2 01T the groundA until it is turned backwards to letthe Aautomobile down.'

I have found that each of the bumper guards may be equipped with theopenings in the top and bottom ends thereof and with an internallythreaded means for only a fewvcents cost.- Only one threaded jack rod isneeded foran automobile since this jack rod may be'threaded through anyof the bumper guards Von the automobile. f -My bumper guardk jack devicethus provides-'a strong, safe and efficient automobile jack which l isincluded inthe bumper guard and which may be operated by any driverwithout fear of having the jack slide out from under the car.

Although the invention has been described inA its preferred form with acertain degree of particularityyit is understood that thepresent'disclosure of the preferred form has been made Vonly by Way ofexample and that numerousl changes v Y the details of construction andthe combinay tion and arrangement of parts may be resorted to. withoutdeparting from the spirit-andthe scope of the invention as hereinafterclaimed.

What isv claimed isz' U-shapedfV cross-section Aopening towards the withopenings located beyond the curved outer surface of the bumper memberthus providing a vertical passageway externallyfofthe bumper member andinternally of the guard' whereby a long lifting screw member may betemporarily and removably inserted downward-1yinto the opening in thevtop portion and outwardly through i the opening in the bottomportion ofsaid guard,l
